Need Help & Recommendations for a dyno

Projects General Guidance

Ok, I'm sure it's been answered on here somewhere but cant seem to find it so here's my plan & what i'd like to end up with. I got a Stuska single vane water brake i'm wanting to convert to computer read out with live data so I can print the pulls to give to customers.

Here's at the least the sensors I wanna collect data from to get started

  1. VSS speed sensor for RMP reading

  2. 100 kg load cell (if I figured it right mine comes up as 75kg but cant find one so I figured 100is best)

  3. The HX711 load amplifier for load cell reading

  4. The AEM UEGO or Spartan 2 wideband sensor

The additional sensors I wanna end up with when all said & done

  1. Bosch BME280 weather station

  2. Spark plug/Cylinder pressure sensor

  3. A stepper motor with driver to do the automatic load or ASME-MXA this type of motor which videos is on youtube that show this motor working with an Adruino

  4. A throttle selonoid to operate it automitically

  5. A solenoid possibly to cut on & cut off a fan when I hit the start pull & it cut off say like 2 minutes after the pull shuts down at the set RPM

With all the info, what all in the arduino line do i need to collect and or run this set up automatically & what software free or purchased is the best to use for this.

I'd like to have it so i can set the minumum RPM & maximum RPM to where i can do an up or down sweep in an adjustable amount of seconds that i can set. Otherwords i set the perimeters, hit a start button onscreen & it automatically makes the pull & stops.

When it comes to microprocessors i'm totally lost in what i need for what i wanna do & how it all wires up plus anykind of coding that has to be done to the software to have these perimeter onsceen to see & change if needed so don't beat me up to bad lol. If anybody has got a setup just like this, has any knowledge of how to make all the work, what i need to make it all work or any other low cost way that would be better then i'm open for suggestions. I've got pretty much all the sensors except cylinder pressure one so thats the reason i was thinking Arduino would be a good way to go. I have looked at a LABjack U6 Pro which they say it will do it with no problem so it would be very appreciated to hear what some say, would do, recommend & steer me through all of it if i needed help. Thanks Ronnie..

Bumping your question after 3 hours is unreasonable. 3 days would be fine. People sleep, you know. And visit the pub. Some of them even have jobs to go to.

I reckon you are asking too many questions all at once. Pick one small piece of your system and get that working - perhaps reading the RPM.

This a complex project .

  1. There is no commercially available software for this on the Arduino for this type of project.
  2. It maybe too difficult a task for Arduino , you are collecting a lot of real time data , there are calculations to do and saving of data....and there is a control element in it too . I think I’d look at Labview on a PC for this sort of job, it won’t be cheap and not a beginners job .

I sleep, work 2 jobs, go to the bar when time permits & multitask many times a day & can still reply so thank you very much for your smart reply that is not needed & have a good day.

It reckon it is you who is being smart.

People here offer their time for free to help you. They are not your servants waiting to dance attendance when it suits you.
